Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency

Dataset used to develop the "Agricultural and horticultural land use" indicator (available at www.stats.govt.nz/indicators/agricultural-and-hort...)

​

This indicator reports on the use of land for primary production purposes, specifically agricultural land uses, such as beef and sheep farming and dairying, horticultural land uses, such as fruit and berry, and vegetable growing, and other land uses, such as forestry. We do this for the period 2002 to 2019.

This metadata record describes an image of land predicted to be at risk of severe mass movement erosion for the South Island. The image was produced using the Highly Erodible Land model that identifies land at risk to the main forms of mass-movement soil erosion in New Zealand: landsliding, gullying, or earthflow erosion. If the land has protective woody vegetation, then it is not at risk (Dymond et al., 2006). The Highly Erodible Land model identifies five classes of land at risk of erosion: (1) High landslide risk – delivery to stream; (2) high landslide risk – non-delivery to steam; (3) Moderate earthflow risk; (4) Severe earthflow risk; and (5) Gully risk. Landsliding occurs on steep slopes where the soils do not have protective tree roots. The slope angle at which land is considered at risk to landsliding depends on rock strength. Where land is steeper than this slope threshold and does not have woody vegetation, it is considered at risk to landsliding. There is no slope threshold for land at risk to gullying or earthflow erosion. Where land is at risk to gullying or earthflow erosion and does not have woody vegetation, it is considered at risk. The different types of mass-movement soil erosion are not ranked in severity, except for earthflow risk which has extreme and moderate classes of risk. Use: These data provide a regional perspective on land at risk of soil erosion.

This data measures the numbers of farmed livestock (dairy and beef cattle, deer, and sheep) over time across New Zealand.

Livestock farming is a widespread land use in New Zealand and is a large contributor to our economy. High livestock numbers and the distribution of livestock across land environments can affect indigenous biodiversity and soil health (eg through erosion, habitat loss, compaction, and nutrient concentration). Water quality can also be adversely affected, as nutrients, sediment, and bacteria from urine and faeces can leach or run off the land into rivers, lakes, and groundwaters. This can affect the health of the aquatic ecosystem, as well as recreation and cultural values associated with rivers and lakes.
